Crews are about half done with the rehabilitation project causing a four-month closure of the historic Concord Road covered bridge.

After 145 years, the structure is undergoing an $800,000 overhaul that Cobb County commissioners unanimously agreed to fund with the 2016 SPLOST, or Special Purpose Local Option Sales Tax.

The bridge and other associated structures were entered into the National Register of Historic Places in 1980.

Located near Smyrna and spanning Nickajack Creek, the covered bridge has started to lean, said the county transportation department. The work started in August.

Now nine weeks in, the Cobb DOT posted some pictures on its Facebook page Wednesday morning. The post said crews have been installing overhead beams and bracings.

“The progress is on track, time is flying by, and this landmark will be open to traffic again before you know it,” the agency said in the post.

With the structure closed, you can still connect to Hurt Road on the southwest side of Concord Road about a half-mile from the bridge.

Take a look at the week-nine progress below.
